"Good afternoon," he said. "I see you have recognized me. That's very clever of you. Most people don't."
Doris was too surprised at first to be able to answer him. But he didn't seem to mind, and went on smiling; while as for Christopher Mark, he climbed upstairs again, just as if the little man hadn't been there.
"I'm afraid I don't recognize you," said Doris at last; "but I'm frightfully obliged to you for saving Christopher Mark."
"Not at all," he said. "That's what I'm for. I'm St Uncus."
Doris frowned a little.
"St Uncus?" she asked.
"Latin for hook," he said. "Excuse me half a moment."
For a flicker of an eyelid he disappeared.
"Just been to China," he said, "to hook another one."
Doris opened her eyes.
